Access the source code from an HTML component

Is there a method to access the source code of a page in the HTML component?
I can't use URLLoader or HTTPService because of cross domain policies, so I need to use the HTML component to load the page, then access the source.

I Need Help to Access The Source Code From A Form to Know the Calculation Formula

Hi,
I Need Help to Access The Source Code From A Form to Know the Calculation Formula. The application is a windows form application that is linked to SQL Server 2008. In one of the application forms it generates an invoice and does some calculations. I just
need to know where behind that form is the code that's doing the calculations to generate the invoice, I just need to get into the formula that's doing these calculations.
Thank you so much.

Hi,
Thanks for the reply. This is a view and [AmountDue] is supposed to be [CurrentDueAmount] + [PastDueAmount] - [PaidAmount]. The view is not calculating [PaidAmount] right . Below is the complete code of the view. Do you see anything wrong in the code ?
Thanks.

How to get the source code of an HTML page in Text file Through J2EE

How to get the source code of an HTML page in Text file Through J2EE?

Huh? If you want something like your browser's "view source" command, simply use a URLConnection and read in the data from the URL in question. If the HTML page is instead locally on your machine, use a FileInputStream. There's no magic invovled either way.

How to get the source code of an HTML page in Text file Through java?

How to get the source code of an HTML page in Text file Through java?
I am coding an application.one module of that application is given below:
The first part of the application is to connect our application to the existing HTML form.
This module would make a connection with the HTML page. The HTML page contains the coding for the Form with various elements. The form may be a simple form with one or two fields or a complex one like the form for registering for a new Bank Account or new email account.
The module will first connect through the HTML page and will fetch the HTML code into a Text File so that the code can be further processed.
Could any body provide coding hint for that

ABAP WD, Read the source code of a html page

Hi all,
I have the URL link of .jsp page and I want to get the source code generated by this page to extract some data for my web dynpro.
How do i solve this?
Thanks

Hi Antonio,
not sure if i understand the question properly.
You want to read html content of http site rendered via jsp.
You can use cl_http_client
to write a simple http client tool.
This tool opens the page. The html content is available to this class.
You can extract the content here.
See the attribute 'response' after making a call.

Phil.

Finding the source code from Jar file

Hi,
I am a beginner java programmer but have been entrusted with learning our company's Java application. The architect of the application is not forthcoming in sharing information and so I need help in tracing the source code for the application. I know where the .jar files are stored but I don't know where the actual .java or .class files are stored.
In the .profile file, I see the classpaths set to various jar files. eg.
CLASSPATH=$PATH:/eaid01_apps/merc01/libs/tools/java/drivers/bin/eaiRun.jar
When I view this jar file with command "jar tf eaiRun.jar", it displays all the files under it. Onc such listing is as following:
citi/eai/EAI.class
citi/eai/Interface.class
I want to go to that specific directory on our file system which is storing these .class or.java file. From what I have learned about packages, I should find some folder called 'citi' ,'eai'.
However I am not able to find these folders anywhere on file system. Is there a way I can find where the actual souce code is by looking at the jar files.
Please help. Let me know if you need more information.
thanks,
Anand.

Is there a way I can find where the actual souce code is by looking at the jar files.No, in general you can't, you should ask the architect that you mentioned earlier. The name of the source file is sometimes stored in the .class file for debugging purposes but that's unlikely going to help you find the files.
You should also ask if he/she has got any documentation of the system. It's often a lot easier to follow documentation written in human language than program code written in a programming language. There could be documentation in a format similar to this: http://java.sun.com/j2se/1.4.2/docs/api/

How to convert the source code in JSP,HTML&BEANS into executable files?

Sir,
We are developing one s/w product in JSP,HTML&BEANS.Now we are in the implementation phase.During the time of Installation,without copying our source code in the customer's site I want to copy the executable files of the entire source codes? Is it possible in JSP,HTML&BEANS?

In theory you can do it even with JSP but the you will be unable to run it on the standard JSP engine. :-)
From other hand, all critical logic should be in the Java Beans or at least in custom tags but not in the JSP code. Then you can protect that code and leave JSP open because there is nothing to steal or break.

An obfuscator can for example rename classes, variables to meaningless names, like one-letter names. And it can make some bytecode that is hard to decompile or just makes the code less readable when decompiled. Some obfuscators might even be able to do something to the code that makes decompilers not work or incorrect decompile code.

I see where I can view the code but not where I can make changes. The coding that is there now was created by the template I chose on Blogger.

How do I access iWeb source code?

I am building a site on iWeb and want to add drop down menus. I can make them in Dreamweaver, but I don't know how to access the full source code of iWeb to be able to add the Spry Menu Bar I have created in Dreamweaver CS3
Can anyone tell me how to access the source code of iWeb?
Can I build a page in iWeb in code?

If so, is it true that it has to be added again each time you publish?
If you are talking about modifying the code in the .html files created when you publish from iWeb, yes, your modifications will be overwritten if you republish, so they need to be added again.

JLundan,
I want to thank you for responding to the thread I started on the forum at java.sun.com. Your solution to my problem of needing to print the code of the html pages that the file I included generates was just what I was looking for. However, I have some further questions to ask, if you don't mind. To clarify my task I should say that your rephrasing of the problem is accurate: "You wan't to display the contents of the HTML file that the web server produces in response of client's request?"
Yes, this is what I need to do, but also it needs to display the source code of that html file that the server produces in response to the client's request. Also, in this case, I am the client requesting that the server return some html file, and I'm not sure where the server is. But the webserver.java file that I shared on the forum is on my local machine. I was wondering if I could modify this webserver.java file at my home so that any html file the server returns to me would automatically display the source code. This is a school project of mine and I am stuck on this one thing here.
Further, where would I put the "foo.html" file so it can be written to?
FileOuputStream fos = new FileOutputStream("foo.html");
fos.write(bytes);
fos.close();
Thanks so much for your help. I look forward to your response, at your convenience.
Regards

How to Write source code of a html page to a File

Using this code i could find the source code of a html page from a web server
import java.io.*;
import java.net.*;
public class SourceViewer{
public static void main (String[] args) throws IOException{
System.out.print("Enter url of local for viewing html source code: ");
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String url = br.readLine();
try{
URL u = new URL(url);
HttpURLConnection uc = (HttpURLConnection) u.openConnection();
int code = uc.getResponseCode();
String response = uc.getResponseMessage();
System.out.println("HTTP/1.x " + code + " " + response);
for(int j = 1; ; j++){
String header = uc.getHeaderField(j);
String key = uc.getHeaderFieldKey(j);
if(header == null || key == null)
break;
System.out.println(uc.getHeaderFieldKey(j) + ": " + header);
InputStream in = new BufferedInputStream(uc.getInputStream());
Reader r = new InputStreamReader(in);
int c;
while((c = r.read()) != -1){
System.out.print((char)c);
catch(MalformedURLException ex){
System.err.println(url + " is not a valid URL.");
catch(IOException ie){
System.out.println("Input/Output Error: " + ie.getMessage());
Iam not much a expert in java .. i could find some commands to write to a file but i dont know where to use those codes , some body please give me some idea ..
thanking you ..

You're welcome. How about awarding them duke stars?
edit: cheers!

Why can't I edit the source code?

Updating an existing site that was created in Front Page. Am using DW CS4. Must be missing something totally obvious, but when I have pages open in split view, I'm unable to edit the source code. Any thoughts? I can make changes to the CSS, but direct editing in the source code seems to be unavailable.

> Is it because I didn¹t download the site through DW, that I can¹t edit the source
code?
No. HTML is HTML no matter who writes it.
This page is definitely a template controlled page, but it is one that has been 'hacked' in the sense that someone has removed the link to the template page from the head of this document (there should be a link to the template page just below the <html> tag). For example, if you look at the code on the about.htm page, you will see this -
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"><head>
And by the way, I will say that this looks suspiciously like a DW page not a FrontPage page....
What edits are you wanting to make to this page?
